YOU said the photograghs were obvious fakes, are you now retracting that statement yes or no?

Both videos referred to above are evidently edited. Pictures extracted from the first video showing that the wall is deformed are apparently taken after the roof starts to fall!! Clever manipulation!

I always trust my own calculations and not those of 200 'experts' or similar. US authorities have got different things wrong many times since 911 and the explanation of the WTC1 collapse is just one in a long row of mistakes.
